Wales Patent of the Month – May 2025

Alleviant Medical Inc. has secured U.S. Patent No. 12290305 for its ‘Transcatheter device for interatrial anastomosis’, a breakthrough in treating heart failure without permanent implants. The new device offers a minimally invasive solution for pressure relief in the heart’s upper chambers, potentially transforming care for millions of patients.

Implant-Free Innovation for Heart Failure

This device uses radiofrequency energy to create a precise hole in the heart’s septum, establishing a controlled left-to-right atrial shunt. Unlike other methods, it avoids leaving any implant behind, which may lower complication risks and improve long-term outcomes. The goal is to reduce elevated left atrial pressure, a key issue in heart failure with preserved or reduced ejection fraction.

Regulatory Momentum and Trial Readiness

The technology has earned Breakthrough Device designation from the FDA. Alleviant is preparing for pivotal trials, including the ALLAY-HFrEF study, to evaluate safety and efficacy in symptomatic patients who have not responded to conventional treatments.

Potential for Widespread Impact

Heart failure remains a leading cause of hospitalization. This solution offers new hope for patients seeking effective therapy without added surgical burden. If clinical success follows, this could mark a significant shift in interventional cardiology.
